What does the AFL-CIO and gay activists have in common? Opposition to marriage.

The marriage protection amendment is producing an interesting alliance of groups on the left.

A coalition of groups have publicly stated their opposition to the Marriage Protection Amendment on the ballot in November 2012.

OutFront, Project 515, and Human Rights Campaign naturally headline the groups opposed to the amendment. Then there's the ACLU, NOW, MPIRG, and a litany of DFL associated groups like DFL Party, DFL Feminist Caucus, DFL Veteran's council, and DFL Senate Districts 38, 62.

Then several religious groups: Unity Unitarian Church, Shir Tikvah Jewish Synagogue, Lutherans Concerned, Catholics for Marriage Equality, and First Univeralist Church of Minneapolis. Their opposition to the amendment neutralizes the left's efforts to marginalize involvement of religious conservatives.

Then the Green Party, Libertarian Party and Independence Party of Minnesota.

The Minnesota Council of Nonprofits which tries to portray itself as nonpartisan.

And let's not forget the pro-abortion NARAL Pro-Choice Minnesota.

And of course the Minnesota Atheists.

And then there's the labor unions. Minnesota AFL-CIO, MAPE, St. Paul Federation of Teachers, AFSCME-Minnesota Council 5, and SEIU. Here's a good reason for the public and union members to become disillusioned with organized labor. They're not just concerned with work place conditions and issues but promoting a leftist social agenda.

Who's on the other side of the issue? The majority of Minnesotans.
